support npm v9

[yshrsmz]

fix: #152

According to the document, npx --offline foo uses locally-cached binary and fails if there's no cached binary.

I'm going to create a PR for action-stylelint once this PR gets merged

[yshrsmz]

npx will print error below if no cache is available. Should we suppress the output?

$ npx --offline eslint --version >/dev/null
npm ERR! code ENOTCACHED
npm ERR! request to https://registry.npmjs.org/eslint failed: cache mode is 'only-if-cached' but no cached response is available.

Hi, I need this pull request to be merged 🙏
I came across an error like this, and I guess, this could be solved with the PR.
